SFP450-12BG Bel Fuse

Bel Power Solutions SFP450 Series is a 450 Watt, power factor corrected (PFC) front-end which provides a 12 VDC output for datacom and other distributed power applications. Its compact size enables mounting in both 1U and 2U height racks. High efficiencies, advanced thermal management techniques, and an internal fan increase reliability over a broad range of operating conditions. Internal ORing diodes facilitate use in hot-swap (plug)*, redundant configurations. Status is provided with front panel LEDs, logic signals and via the I2C management interface bus. The SFP450 Series meets international safety requirements and is CE marked to the Low Voltage Directive (LVD). Wide input voltage range (90-264 VAC) with PFC 3 High power density, 9 W / inch 1U or 2U height configurations Active current share with ORing FET IC interface status and monitoring Standby voltage of 3.3 VDC 3 A Overtemperature, overload, and overvoltage protection Status LEDs: AC OK, POWER GOOD, PS FAIL Datacom Distributed Power Systems * Proper hot-swap (plug) operation instruction: Power supply is not intended to be inserted into the system with AC cord already applied. Alternatively, if there is an application where power supply insertion with AC cord is required PS ON must be toggled or AC recycled after insertion into the system to reset the power supply. 2 SFP450 Series MODEL INPUT VOLTAGE OUTPUT VOLTAGE OUTPUT CURRENT STANDBY OUTPUT OUTPUT POWER SFP450-12BG 100 240 VAC 12 VDC 36.6 A 3.3 V/ 3 A 450 W SFP450-S101G* 100 240 VAC 12 VDC 36.6 A 3.3 V/ 3 A 450 W *SFP450-S101G is the preferred version as the over temperature protection is independent of the current.
